Have you lost a camera or had one stolen? You just may be able to recover it with the help of 2 web based services.
Stolencamerafinder.com and cameratrace.com will search the web for images with the serial number of the cameras that shot them, helping to re-unite owners with their lost and stolen cameras. Both work by looking for the serial numbers embedded in images uploaded to services such as Flickr and 500px. CameraT race, which costs $10 per camera, now includes a monitoring service that updates you if new images are posted. Stolen Camera Finder, meanwhile, requires only that you drag-and-drop a file from your camera for it to read the EXIF and start searching for public photos with their metadata intact.
